My mom came from a Jewish background, and my father from a Christian one. Early on, I was under the impression that Judaism and Christianity were close enough to the same things. As it became harder and harder to hold onto this misconception, I chose Judaism. During this time however, I experienced a lot of doubt. There have been times where I told myself atheism must be correct.
I always knew the Greek myths, even in preschool a bit. I later got into others. I became more interested in Pagan beliefs first by learning about the Sumerian Flood story, of Asherah who was worshiped as the consort of the Jewish God. I was fascinated by the Canaanite God El, and Arabic Allah- both cognates for a common semitic term for a supreme deity... cognates of "Elohanu" and "Elohim". All etymologies from a proto-semitic pagan pantheon. I remembered thinking of the use of the word "Elohim", plural, in Genesis. Gradually, it began to seem to me that virtually the whole world was once Polytheistic/animistic- and that the only doctrine that really opposed this idea without hope of compromise was Abrahamic monotheism. Between the two, it looks a lot more like the latter was the deviation or anomaly, not the former. Polytheism developed independently all over the world. Monotheism emerged from the levant not too long ago,
